IMPROVEMENT IN FEED-GASES FCR CYLINDER PRINTING-PRESSES.

Specification forming part of Letters Patent No. 162,993, dated May 11,1875; application iiled January 12, 1875.

To all whom it may concern:

- Be it known that I, HENRY BARTH, of Gincinnati, in the county ofHamilton and State of Ohio, have invented certain Improvements inPrinting-Presses, of which the following vis a speciication:

My invention relates to stop cylinder printing-presses; and consists inthe construction and arrangement of a feed gage or guide for the sheetson the cylinder', as will be more fully described hereinafter.

The drawing represents the cylinder of a printing-press with myinvention applied, and the table from which the sheets are fed.

E is the table, from which the sheets are fed to the cylinder C. Ais myguide, at`

tached to the cylinder by the plate D, in the manner shown, and alongwhich it is capable ot' sliding from side to side of the cylinder, andis fixed at any point by the screw B; The slot and screw a permit theforward and backward movement or adjustment of the guide. The cylinderis shown at the stopping-point. The sheets are slid down from the tableE, against the guide A, and are then caught by clamps, in the usualmanner, and carried around to the type by the revolution of thecylinder. At d is a scale for adjusting the guide.

In the ordinary machine, a guide is fastened on a rod extending acrossthe face of and separate from the cylinder, which necessitates thesheets`being led over tongues to bring them up against the guide. Theconsequence is that the paper, when pulled over tongues onto thecylinder, by the revolution ofthe latter, is wrinkled, and thereforedoes not print.

In my d'evice tongues are unnecessary, as the guide is on the cylinder,and the paper comes to the type perfectly smooth and liat. Moreover, asthe guide is attached to the cylin der, the sheets are against it untilthey are printed and delivered, and therefore cannot get out of place.

What I claim as my invention is- .In combination With theimpresson-cylin der of a printing-press, a gage or guide, When said gageis made vertically and circumferentially adjustable upon the face of thecylinder, substantially as shown.

Attest: HENRY BARTH.
